1. Structure of Metallurgical Coke of NUT COKE of 5 -15 mm Description:
Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.
Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.
Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.
On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

- Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
- Coke GB/T 1996-2003, volatile coke is the most difficult to do
- Q:Coking coal, coke, coal, steam coal what is the difference?
- Coal is used to generate electricity, which is used to burn coalPower coal is generally only coal
- Q:Coke is divided into several kinds of specifications ah
- (Lord Jiao Meilian) {for precision casting and ductile casting for} fixed carbon above 86; sulfur ash is below 0.5; 12; 1.5: volatile fiddle coke grain size 4cm--8cm or above 10cm: fixed carbon furnace for {}} setting common casting coke particle size 25cm:{for precision casting and ductile casting for 3 more than 88 tons of sulfur ash; 0.5; 10; 1.5: volatile foundry coke particle size 25cm:{type applicable to the above all high precision ductile casting export and international index: {8cm} fiddle coke for common casting and casting products such as strict fire pump fittings; fasteners such as high fixed carbon above 788385} sulfur: {for copper, aluminum, plastic, chemical coke} fixed carbon above 83 gas coal coke: {for carbon monoxide gas extraction, rich gas} fixed carbon about 78 coal coke: {casting parts annealing, Coke, coke, civilian chemical copper, aluminum, plastic} fixed carbon about 65 coke, coke coal: {civil casting parts of annealing, chemical coke}
- Q:What are the requirements for the quality of coke in blast furnace smelting
- 4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%.5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error.6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.
- Q:What is the use of petroleum coke
- Petroleum coke, petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining.
- Q:Which heroes know, please give the source of the data.
- From the production equipment and technology of the popular view, a ton of coke oven gas produces about 400 cubic meters, of which about 200 cubic meters of coke oven returned through the pipeline used for coking heat source, the remaining more than and 200 cubic meters was emptying, "or the lantern".
- Q:Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
- It is a solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure.
- Q:What are the main uses of coke
- The utility model is used for casting blast furnace smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc..
- Q:What is the density of coke?
- Do you want to transport by rail? Ha ha, you might as well ask the freight forwarding clerk, he / she will tell you the various models of the volume and the weight can be installed, the conversion of the density of the pile is more accurate.
- Q:What are the national standards for grade two coke?
- Two national standards for metallurgical coke: total sulfur: 0.61 - 0.80; ash: 12.01 - 13.50
